Lydia Wantz of Carroll Co.,Md.

Looking for the parents of Lydia Wantz born 1/4/1827 in Carroll Co.,Md.. Lydia married William Meyer on 10/2/1851 and they had five children. Their marriage record spells her name Vantz but church records spell it Wantz. Don't know which is correct? They are buried at Pleasant Valley Cemetary. Any help will be appreciated.
